MACHINE FOR PRINTING AND MOISTENING ADHESIVE WRAiPING-TAPE.

Specification of Letters Patent.

Application filed April 23, 1914. Serial No. 838,847.

Illinois, have invented certain new and useful Improvements in Machinesfor Printing and Moistening Adhesive Wrapping-Tape, of which thefollowing is a specification.

This invention relates to machines for printing and moistening wrappingtape and its object is to provide a machine of simple and inexpensiveconstruction, which comprises few parts, which is easy to operate andwhich will not readily get out of order. In addition to the generalobject of the invention it also has in view to provide simple means foradjusting the tension on the spool of tape, for adjusting the tension ofthe printing roll and for moistening the free end of the tape before asection thereof is removed.

With these and other ends in view the invention consists of the novelconstruction and arrangement of parts hereinafter described andillustrated in the accompanying drawings in which Figure 1 is a sideelevation of the machine, partly in section and partly broken away, andFig. 2 is a detailed sectional view through the tape spool showing theadjusting means.

Referring to the drawings, a suitable frame 3 in which all the parts aremounted comprises two side members 4, 5 which are held together andspaced apart by three bolts 6.

The tape 7 consists of a paper strip coated with adhesive on one sideand wound in the form of a roll 8 which is mounted in a spool supportedto revolve on one side 4 of the frame which extends upwardly for thispurpose. A shaft 9 provided with a shoulder 10 projects through theframe side 4 and is screw-threaded to receive the nut 11 by which theshaft is rigidly fixed to the frame. A sleeve 12 is arranged on theshaft and its inner end abuts against the shoulder 10. A spool end 13 isrigid with the inner end of the sleeve and engages the shoulder 10.Another spool end 14 is loosely mounted on the sleeve on the oppositeside of the roll 8 and a nut 15 is screwthreaded on the outer end of thesleeve to engage the spool end 14. By adjusting this nut 15 the spoolends may be caused to engage the sides of the roll of tape. The

shaft 9 is interiorly threaded at the end ad acent to the nut 15 toreceive a screw 9' WhlCll engages the outer end of the sleeve 12,whereby the ten ion of the tape may be 80 adjusted by tightenin orloosening the sleeve on the shaft. To place a roll of paper in themachine the nut and screw 15 and 9' and the spool end 10 should beremoved.

The paper passes down from the roll at the front of the machine to andaround an impression roll 16, thence up and over the paper roll and thendown and under a guide roll 17 and forwardly over the moistening roll 18and beneath the cutting edge 19. A printing roll 20 is yieldinglysupported beneath the impression roll 16 to print upon the paper as itpasses around the impression roll. This printin roll is supplied withsuitable type and 1s inked by the gravity inking rolls 21 removablymounted in the frame and operating freely therein. The printing roll ismounted on a shaft 22 which projects through slots 23 in the sides ofthe frame and spring arms 24 engage the pro jecting ends of the shaftand yieldingly press the printing roll against the tape, so that saidroll will turn with the impression roll and the tape to print upon thetape. The yielding spring arms 24 are parts of spring wires 25 which arecoiled on the studs 26, in each side of the frame, and which pro ectrearwardly to engage rack teeth 27 on the sides of the frame, wherebythe tension of the spring arms may be adjusted. I

The moistening roll 18 is mounted in the frame to work in; a bath ofwater contained in a removable trough 28, so that the adhesive side ofthe tape will be moistened in passing over the roll 18 as the tape isdrawn over the machine. A cutter 19 is arranged adjacent to themoistening roll so that when a strip of tape has been drawn outward itcan be easily removed by tearing it along the cutting edge 19.

It will be observed that the end of the tape always extends forwardly ofthe moistenlng roll and if the machine was not used for some time theadhesive on this rojecting end of the tape would become ry and notadherent when a section of the tape was later removed. In order tomoisten this projecting end of the tape before a section of the tape isremoved from the machine I provide a sponge 29 located in a PatentedNov. 3, 1914.

small compartment 30 at the forward end of the trough 28 and a smallhole 31 in the partition 32 which separates this sponge compartment fromthe water compartment 33, so that water may trickle through and keep thesponge constantly moist. Just before a section of the tape is removedfrom the machine the projecting end should be pressed into engagementwith the sponge to.

moisten the adhesive thereon after which the'tape can be withdrawn asdesired.

It will be observed that all the parts of the machine are removablymounted in the frame so that they can be readily removed as occasion mayrequire and that the adjustment of the various parts can be regulated asdesired.

I claim:

In a machine of the character described, the combination of a frame, aspool for holding a roll of tape supported in 'the upp nnaoea per partof the frame, an impression roll mounted in the frame below .the spool,a printing roll mounted in the frame below the impression roll, ashaftfor said printing roll having its ends projecting through slots inthe sides of the frame, studs projecting outwardly from the sides of theframe, spring wires mounted on said studs and having arms projectingforwardly beneath the shaft for the printing. roll to press said rollupwardlyagainst the tape on the impression roll, and rack teeth on thesides of the frame, said wires being coiled on said studs and rojectingrearwardly .to be engaged with said teeth, substantially as described.
